Abstract: ABSTRACT OF THE DISCLOSURE         A highly efficient boiler is made up of a housing containing upper and lower left and right water manifolds.  Tubes connect the left manifolds and other tubes the right manifolds.  The tubes are bent toward one another to  form a plurality of  superposed chambers through which combustion gases must successively flow, from front to back in one chamber and from back to front within the next.  Baffles may be provided in each chamber to cause the gas to traverse a sinuous path from left to right and right to left within each chamber.  Adjustment of the baffles can be effected during operation to keep the combustion gas exit pressure or temperature or flow rate constant notwithstanding changes in the liquid flow rate through the tubes or the rate of combustion of fuel in the lowermost chamber.

Patent CA-2037797-A1 (CA)
Inventor: ALTHOUSE JAMES J III
IPC: B01F25/64
Filed: 1991-03-08
Abstract: A method and apparatus useful for dispersing solids in liquids. A mixer device implementing the method is capable of continuously mixing solid and liquid materials whose physical properties may be allowed to vary over a wide range of values without degradation of product quality. Basic components of the mixer consist of a rotatable turbine 22 enclosed in a casing 20. The turbine is configured so as to open an "eye" in the rotating liquid where solids may be introduced into the liquid stream. Make-up liquid is supplied at a controlled pressure to the turbine through an annular suction inlet. The mixer is configured so that the ratio of solid material to liquid material remains constant from their initial contact with one another to their discharge from the apparatus as a mixed product. A more thorough mixing of solids and liquids is achieved by directing the flows of materials by the method described, and the reliability and dynamic range of the mixer are significantly improved with respect to the performance of devices taught in the prior art.

Filed: 1991-03-26
Abstract: A toothbrush whose tufts comprise three distinct groups of rows, with each row oriented transversely to the longitudinal axis of the head. The tufts of the first group are the shortest. The endmost tufts on each row of the second kind tilt laterally outwardly by about 12 degrees. The tufts of the third group are nearest the end of the head farthest from the handle and diverge from each other.        In one embodiment, each tuft of the third kind tilts laterally at an angle of about 30 degrees and forwardly at about 14 degrees.        In a first embodiment, each row of the first group comprises a single, wide tint. In a second embodiment, each row of the first group has a plurality of laterally spaced round tufts. In a third embodiment, each row of the first group comprises a plurality of laterally spaced quadrangular tufts. All of the tufts may also be considered as defining four functional groups of tufts, with each of these four groups performing a specific function during brushing. The arrangement and orientation of the tufts yields a uniform cleaning action substantially independent of brushing direction or technique.
Patent CA-2039366-A1 (CA)
IPC: G06F19/00
Filed: 1991-03-28
Abstract: An object, such as a robot, is located at an initial state in a finite state space area and moves under the control of the unsupervised neural network model of the invention.  The network instructs the object to move in one of several directions from the initial state. Upon reaching another state,  the model again instructs the object  to move  in one  of  several  directions.   These instructions continue until either:   a) the object has completed a cycle by ending up back at a state it has been to previously during this cycle, or b) the object has completed a cycle by reaching the goal state.  If the object ends up back at a state it has been to previously during this cycle,  the neural network model ends the cycle and immediately begins a new cycle from the present location.  When the object reaches the goal state, the neural network model learns that this path is productive towards reaching the goal state,  and is given delayed reinforcement in the form of a "reward".  Upon reaching a state,  the neural network model calculates a level of satisfaction with its progress towards reaching the goal state.  If the level of satisfaction is low, the neural network model is more likely to override what has been learned thus far and deviate from a path known to lead to the goal state to experiment with new and possibly better paths.  If the level of satisfaction is high, the neural network model is much less likely to experiment with new paths.  The object is guaranteed to eventually find the best path to the goal state from any starting location, assuming that the level of satisfaction does not exceed a threshold point where learning ceases.

IPC: G03F1/72
Filed: 1991-04-12
Abstract: The disclosure deals with color filters used in liquid crystal devices and, more particularly, with the repair of defects.   When  a  given defect  is  one  color,  the defective  portion  is  filled  with  a  negative type photosensitive resin of the same color as the defective pixels.   When a defect extends over pixels of various different colors,  the defective area is filled with a negative type photosensitive resin of gray.   Repair is readily effected since  self-alignment can be  achieved using the filter as a photomask.
